 <h1>SIMULATION</h1>
 <h3 style="text-align:left; max-width: 60%;margin-left:0;">
  <ul style="margin-left:0;">
   <li>In XSCHEM a schematic usually contains all the details needed to run a simulation.</li>
   <li> When a schematic is correctly drawn just generate the netlist pushing the Netlist button, and then start simulation
        by pressing the Simulate button.</li>
   <li> XSCHEM has bindings to waveform viewers as well as simulators. Press the Waves button after simulation
        is completed to view the results.<br>

   <li style="clear: both;"> With proper netlisting attributes on leaf cells the same design can be simulated unchanged in Spice, Verilog, VHDL.
   <li> DC Operating point information back-annotation into the schematic is possible.</li>
